This kit contains the bushings and sleeves required to replace the stock differential mount bushings on the 1990-1997 NA MX-5 and 1999-2005 NB MX-5.

Helping to keep the drivetrain properly aligned is an important benefit of Prothane polyurethane bushings. Factory bushings tend to wear out, with the resultant sloppiness putting the driveline in a potential "bind" condition. Controlling horsepower benefits acceleration and handling.
